propriate support, adjacent "to the edge B,r.andtope'rative parts thereon in conven 'ient juxtaposition to. the user of the Vise without obstruct-ion by orinterference with such means of support. The base plate B may. be considered-as the supporting means for. thearticle to be clamped; I

y The left hand portion of the parallel standards '13., B, are'for med with sockets b,.i b', for. the reception and support of twin gripping-jaw plates J, J the. vertical edges 'of which are bevelledor rounded convexly to .fit into. concavities constituting .the grooves; or sockets b; b, saidv gripping-j aw plates i J J being removable upon occasion, I asfor replacement or substitution by others v formed "with teeth or serrations j, j, adapted toethe reguirementsof the work. to be ac complished, said serrated edges j,-j,. of the jaws J J being concave, 0r convergent as related to veach other, as indicated. more ntervniiigfbtween.the sockets bri b, in which the, gripping-jaw plates J, J, are positioned, is aplatform 11 integral with the base B and standards B,,B", said platform byhaving a fiat :npper surface adapted to V functionasa rest and-support for. a bolt j head,- nut, or analogous, object, or in-factfif any element to be'treated having a flat surparticrilarlyiin Figs. 1,3 and 5 of the draw-. ingsp v i face for;v contactual engagement withgsaid platform 6, as indicated foriinstance; in

Fig; 7,' of the drawings, (in which abolt head: 7a is shown aslplositioned on the plat form 5%,) thusrendering' my improved chain vise device,=. suitable not only tovthe accommodation and support; of pipes, rods',pand

other analogous objectsof circularfcrosssecytion, but likewise to the treatment of objects K of angular configuration, -,thereby '1 greatly ,increa'sing the'scope of utilityof the vise,

considered in a unitary sense.

'Projecti ngfrom-the left hand ends of the I standards B B and from the medial plat- "fornr 6*, are lateral lugs 6 b the undersides of which are formed with concavitiesj bflwhich "function as fulcrum bearings for contactualflengagement wlth the protuberant. ends of the chainrlink pintles 0. as indicated more especially in Figs. "1 and 2,- of the drawings, the clamping chain G,

being o'fith plate-link type in which 'said pintles function as the pivotal connections between the link plates in a manner well known in the art. The lugs 6 support the of the clamping chain G, is pivotally attached to the lower and inner end of an adjustive tightening screw S, upon which is mounted a power nut N. The tightening screw passes through an abutment or bearing sleeve 19 between and integral with the right hand portion of the standards B, B and extending upwardly therefrom at an angle to the base B, said power nut N being provided with an operative hand lever IJ, by means of which the nut may be conveniently manipulated. V

A novel feature of my construction and arrangement of parts is the interposition between the tightening screw S, and nut N,

and the gripping jaws J, J, and platform Z)",'0f a chain deflector D, preferably consisting of a roller mounted on a fixed axis between the standards B, B, as will be understood by reference particularly to Fig. 3, of the drawings, although any equivalent deflecting medium and surface may be substituted with substantially like results, such as a rigid bar with'convex under surface for, contact with the chain, although the roller is desirable as a means of reducing frictional resistance to a minimum degree.

By the prov1s10n of the deflector D, I

' am enabled to position the tension screw S,

is mounted.

and nut N, at a suitable angle upward to facilitate manipulation thereof entirely from above and untrammeled and unrestricted by the support on which the chain vise Hence said deflector D, may be of the modified construction indicated in Fig. 8, of the drawings, consisting of a solid or fixed cross bar or web between the opposed innersurfaces of the standards B,

B, and integral. therewith, formed with a convex surface (Z, for contactualengagement with the clamping chain in contra-dlstlnction to the rotative convex surface d, of the I deflector shown particularly in Figs. 2 and 3, of the drawings.

By affording free and unobstructed access to the manipulative hand lever L, well above, and upon the right of my chain vise and its support I obviate all danger of injury or inconvenience to the hand of the operator, and facilitate the practical operations in connection therewith. Furthermore by my construction and arrangement of parts of the device, the view of the operator thereof is free and unimpaired in so far as extreme ous objects are concerned; and the device, as a unit, occupies a minimum of space con- 1'. A chain vise of the character designated comprising a base, means thereon for supporting an article to be clamped, a clamping chain, means for holding one end of said chain, an adjustive tightening screw connected with the other end ofsaid clamping chain, a stationary abutment sleeve projecting from said supporting means and inclined upwardly and outwardly at an angle to said base, a power nut engaging said screw and bearing upon said abutment sleeve for moving said screw in an upward and outward direction to tighten said chain, and a deflector interposed between said adjustive tightening screw and the means of support for the article to be clamped.

2. A chain vise of the character designated comprising a base, parallel standards extending therefrom for, supporting an article to be clamped, a stationaryabutme'nt sleeve on said standards, said sleeve being inclined upwardly and outwardly to said base, a clamping chain, means for holding one end of said chain, an adjustive tightening screw connected with the other end of said clamping chain, a power nut engaging said screw and bearing upon said stationary abutment sleeve for moving said screw in an upward and outward direction to tighten said chain, and a deflector interposed between said adjustive tightening screw and the means of support for they article to be clamped, said deflector consisting of a roller mounted on a stationary axle supported between said parallel standards.

3. A chain vise of the character desig-v nated comprising a base, parallel standards extending therefrom for supporting an 'screw in an upward" and outward disistent with its functions and capacity for rection to tighten said chain, and a deflector interposed between said adjustive tight-- ening screw and the means of support for the article to be clamped, said deflector being formed with a convex chain-bearing surface positioned between said parallel standards.

4:. A chain vise comprising a base, parallel standards extending from said base, a platform intermediate said standards, a clamping chain, means for holding one end of said chain in alignment with said platform,

an abutment projecting beyond the edges of said standards and inclined upwardly and outwardly atan angle to said base, and

means'inclu ding a member mounted in said abutment for movement in an upward and outward dlrectlon to tighten said chain around an article resting upon saidstandards, the, paths of movement of said member being wholly on the same side of the base,

as said standards.

- I 5. A chain Vise comprising a base member, parallel standards extendmg from said base, said standards being adapted to re ceive an article'to be clamped, a clamping chain, means for fastening one end of said chain, an abutment projecting upwardly and outwardly beyond the edges of said standards, and means including a member mounted in said abutment for movement in an upward and outward direction to tighten end of said chain, a hollow abutment projecting upwardly and outwardly beyond the side of I clamplng chain, means for-"fastening Lone edges of said standards at a point removed.

from said gripping jaws, and means including a member mounted in said abutment for movement in an upward and outward'direction to tighten said chain about an article resting on said gripping jaws, the path of "movement of said member being wholly on T the same side of the base as said standards. a
